GREASE-DRUM. f

vTo'tllfwtom z't may concern. c 'f A. SEARLE,-a citizen of the United States, residing at Council VBluf'I`s,fin the county of Pottawattamieand State of Iowa, have invented a certain new and useful Improvement in Grease-Drums, of which the following isa Y A tension D1 is bored to receive the lowerend Yof ajvertical drive-shaft F and servesfas a specification. u Y j The invention relates to drums in which heavy oils or triansmissiongreases are contained and transported,'having an inclosed pump by which the contents may be delivered as required,V and the object of the invention is to "provide simple pump-operating mechanism which shall bei economical in manufacture,easily installed, and positive and eflicient in operation. Y

, The invention consists in certain novel features and details of construction and arrangement by which the above and other objects are attained, to be hereinafter described and claimed. 4

The accompanying v of this specification and show the invention as it has been carried out in practice. f

connections to the pump-shaft, and is partly in elevation.

Similar letters of reference indicate the same parts in all the ligures.

A is the cylindrical shell or body of the drum, of heavy sheet steel as usual, having a closed bottom A1, and flanged top A2 adapted to receive a close fitting cover A3 held in place by4 any suitable means, not shown.

B is a bar extending across the interior of the drum near the bottom A1, serving to support a rotary` pump C of any approved type secured thereon and having its suction orifice located as low as practicable so as rto drawl upon the contents near the bottom of drawings .form a part` i i i shaft` F in theispace between thev extenslon 1 G1 and branch G2. y

On the drive-shaft F is a beveled pinion F1 inrmesh kwith the wheel E, seeV t its upper end thevertical drivefshaft VF is inclosed by a'depending tubular extension G1 from an angular casting kG having a horizontally disposed branch G2 extending c across the axial line of theextension G1, as

shown in Fig. 3. The branch-GZ'has in: its under face a recess g in axial alinement with f the bore 'inthe extension G1 and receives thev Vupperfend ofthefdrive-shaft F. A beveled' pinion F2 is secured on the upper end ofthe "H-'is the' operating-shaft extending 'diaf Imetrically across the'drum near -the top,

with its inner-endlsupported ina bossor thimble A? onV- the interior of the drum, and its outer squaredy end Hl projecting into-a socket A5 opening to the exterior of the drum and adapted to permit the application of a crank, not shown, to the squared end H1, as will be understood.

The operating-shaft H passes through a stuing-box J on the inner end Y of the socket A5` and through the Ihorizontal branch G2 of the casting G, and carries a beveled pinion H2 in mesh with the pinion F2V secured to the shaft F. Collars H3 H4 hold the shaft H against movement axially.

The delivery pipe C2 of the pump extends Y is applied on the squaredend ofthe operating-shaft H and the latter turned, the motion being transferredv throughv jthe`v beveled n' f pinions F2 H2 to the drive-shaft vE, and

through the beveled pinion F1 and gear WheelsE to thepump-shaft C1.

It Will be noted thatthe castings D and'G are supported solely by the shafts which .they inclose. The long branch G2 of the casting -G insures thelatter againsthorizontal torsional movement, yWhile the extension G1 and. recess g vform ,a .long bearing for the upper end of the cdrive-shaft -F above and below the pinion F2 and the said shaft F is held against* vertical movement. vAt Ythe .lov'verend the sha'ftgF/inds along bearing and step in the. extension D1 of the casting orfsleeve D Whichfis mounted onthe pump- ,shaft C1 and confined thereon by the beveled `bar B extending on a chord across the drum,

but it maybe mountedl on a base secured to the bottom` A1 or otherwise firmly held above 'such bottom.y f i kIclaimz--- v .Y f 1.
